To all whom it may concern:

Be it known that I, WILLIAM SCHAAKE, a

citizeii of the United States, and a resident it has for its object toso construct and arrange the parts of a truck that the wheel base of thevehicle may be of any desired and reasonable length, without interferingwith movement thereof upon curves in the track.

Figure 1 of the accompanying drawings is a view, in side elevation, of alocomotive having a truck constructed in accordance Fig. 2 is a top planview of a portion of the vehicle truck of Fig. 1, some of the partsbeing broken away sake of clearness of illustration. Fig. 3 is avertical sectional view, on the line III- III of Fi 2, and Fig. 4: is aview, similar to Fig. 2 but showinga modified structure.

The vehicle truck comprises; a main frame 1 that supports a cab or carbody 2, the said frame comprising cast or forged side trusses orinembers3, end members t and I- beam cross members 5. The frame 1 is resilientlysupported by means of springs 6, 7 and 8, the springs 6 and 8 beingsecured to the upper ends of posts 9 that project through openingsintheside members of the frame and are capable of reciprocating motionwith respect to the frame. The posts 9 are pivoted at their lower endsto feet 10 for which seats 11 are provided upon the upper sides ofhousings 12 for journal bearings 13 upon the ends of axles 14 that carrydriving wheels 15 for the vehicle and are surrounded by propellingmotors 16. Upon the interiors of the bearing hpusings 12' are cross-webs17 that supportbearing plates 18 against the ends of the driving axles,so that movements of the driving xles longitudinally of their axes willalso .efi'ect movement of the bearings 13 and the housings 12. The axlesare also provided with shoulders that engage the inner ends of thebearings 13'and assist in transmitting longitudinal movements of theaxles to the bearing housings. The housings 12 are secured to auxiliaryframes 19 the inner ends of which are pivoted to brackets 20 that .areattached to the I-beam cross members 5 of the main frame of the truck.The housings 12 are provided, upon each side, with spaced wings a orlates 21 between which are disposed vertical guide bars 22 thatconstitute parts of the main frame of the truck. The opp0sing faces ofthe adjacent guide bars, as well as the corres ondin housings wit -whicthey are adapted to enga e, are inclined at angles to the axes of 1 theriving axles, or are otherwise suitably shaped to permit, not only) ofrelative vertical reciprocating motion etween the housing and. the mainframe, but also of relative faces of the bearing oscillation betweenthe. main and auxiliary frames of the truckabout their pivotalconneotion and within the limits of the clearances between the guidebars 22 and the wings 21 upon the bearinghousings.

When the vehicle is traveling upon a straight track, the feet 10 eltherrest squarely upon the seats 11 providedtherefor upon the bearinghousings or rock.

slightly because of irregularities in the track. When the vehicleoperates upon a curved portion of the track, however, the

-auxiliary frames 19 and the parts carried thereby are caused tooscillate with respect to the main frame of the truck, with the resultthat the feet 10 are raised at one side from the seats 11, therebyraising the posts 9 against the pressures exerted by the weight of themain frame of the truck and the parts carried thereby, which pressurestend to restore the auxiliary frame and the parts carried thereby to theoriginal and normal positions thereof with respect to the main frame.

' In Fig. at, a considerable degree of rectilinear longitudinal movementof the driving axlesispermitted without the employment of an auxiliarytruck frame, the bearing.

housings 25 being guided in their movevments by wearing pieces 26carried by the side members 27 of the truck frame and limited in theirmovements by stops 28 formed integral with the housings. The remainderof the structure is substantially like that shown in the other figuresof the draw inns.

I claim as my invention:

l. A vehicle truck cmnprising a frame, an axle hearings therefor, a footseated upon each hearing directly above the axle, vertical postspivotally secured to the respective feet, and springs supported uponsaid posts and ha ring; their ends connected to said frame.

1A \ehiele truck comprising a main frame, an auxiliary 'l'rame pivotedthereto, an axle, hearings therefor carried by the auxiliary frame, feeseated upon the bearings, and supporting posts for the main framepivotally secured to the feet.

23. A vehicle truck comprisinga.main frame, an auxiliary frame pivotedthereto, an axle, bearings therefor carried by the auxiliary frame,feetv seatedupon the bearings, supporting posts for the main framepivotally secured-to the feet, the axis of the pivot being disposedtransversely of that of the axle, and resilient means interposed betweenthe posts and the main frame.

at.' A .vehicle truck com rising an axle, bearings therefor havingate'ral faces inclined to the axis of the axle, a main frame providedwith faces corresponding to and adapted to engage the inclined faces onthe bearings, an auxiliary frame pivoted to the main frame and carryingthe axle bearings, springs having their ends connected to the main rame,posts beneath the middle portions of the springs, and feet pivoted tothe lower ends of the posts and resting in seats on the axle bearingsdirectly above the axles.

In testimony whereof, I have hereunto subscribed my name this 31st dayof JanyL,
